Selected AbstractsIncreased prevalence of cardiovascular disease in Type 2 diabetic patients with non-alcoholic fatty liver diseaseDIABETIC MEDICINE, Issue 4 2006G. Targher Abstract Aims, To estimate the prevalence of cardiovascular disease (CVD) in Type 2 diabetic patients with and without non-alcoholic fatty liver disease (NAFLD), and to assess whether NAFLD is independently related to prevalent CVD. Methods, We studied 400 Type 2 diabetic patients with NAFLD and 400 diabetic patients without NAFLD who were matched for age and sex. Main outcome measures were prevalent CVD (as ascertained by medical history, physical examination, electrocardiogram and echo-Doppler scanning of carotid and lower limb arteries), NAFLD (by ultrasonography) and presence of the metabolic syndrome (MetS) as defined by the World Health Organization or Adult Treatment Panel III criteria. Results, The prevalences of coronary (23.0 vs. 15.5%), cerebrovascular (17.2 vs. 10.2%) and peripheral (12.8 vs. 7.0%) vascular disease were significantly increased in those with NAFLD as compared with those without NAFLD (P < 0.001), with no differences between sexes. The MetS (by any criteria) and all its individual components were more frequent in NAFLD patients (P < 0.001). In logistic regression analysis, male sex, age, smoking history and MetS were independently related to prevalent CVD, whereas NAFLD was not. Conclusions, The prevalence of CVD is increased in patients with Type 2 diabetes and NAFLD in association with an increased prevalence of MetS as compared with diabetic patients without NAFLD. Follow-up studies are necessary to determine whether this higher prevalence of CVD among diabetic patients with NAFLD affects long-term mortality. Diabet. Med. (2006) [source] Endovascular stent implantation for treatment of peripheral artery diseaseEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 3 2007M. Schillinger Endovascular stent implantation is a rapidly emerging technology for treatment of arterial obstructions in the entire circulation. During recent years, several randomized studies evaluated the effects of stenting in lower limb arteries. We herein provide an overview on data of trials in the iliac and femoropopliteal vessel area discussing the benefits and limitations of endovascular stents. In the iliac arteries, midterm and long-term data from one randomized trial including analysis on patency, clinical outcomes, cost-effectiveness and quality of life indicate that balloon angioplasty with selective stenting remains the therapy of choice for endovascular revascularization. In the femoropopliteal arteries, balloon-expanding stents were not superior to balloon angioplasty for treatment of short lesions, and self-expanding nitinol stents also failed to show a beneficial effect in short lesions below 5 cm. However, including longer lesions, one randomized trial indicated a beneficial effect of nitinol stents in lesions with a median length around 10,12 cm. Further studies and longer follow-up intervals are needed to confirm these data. Meanwhile, balloon angioplasty with optional stenting also remains the recommended endovascular approach for the femoropopliteal segment. [source] The Anatomy of the Arterial Supply of the Thoracic Limb of the Porcupine (Hystrix cristata)ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 5 2001Sadik Yilmaz The aim of this study was to investigate the anatomy of the arterial supply and branches of the thoracic limb of the porcupine. With this aim, five (three male and two female) adult porcupines were used. The vascular tree of the thoracic limb was injected through the common carotid arteries with coloured latex. The a. thoracica externa arose from the a. axillaris at the level of the fourth rib. It divided into two branches and went to the m. cutaneus trunci and the m. pectoralis ascendens. The a. subscapularis came off the a. thoracodorsalis. Later, the a. circumflexa humeri caudalis et cranialis, the three muscular branches and the a. circumflexa scapulae arose from the a. subscapularis. The a. profunda brachii arose together with the a. bicipitalis from the same truncus. The a. collateralis ulnaris left from the a. brachialis independently. Rete carpi dorsale was formed by the a. radialis, the r. carpeus dorsalis of the a. collateralis ulnaris and the a. interossea caudalis. Arcus palmaris profundus was formed by the r. profundus of the a. interossea caudalis and the r. palmaris profundus of the a. radialis. In conclusion, despite a partial resemblance to that in the rat, the distribution of the thoracic limb arteries in the porcupine was found to be completely different from that of other mammals. These findings represent, to our knowledge, the first study on the distribution of thoracic limb arteries in the porcupine. [source] Rupture of a peripheral popliteal artery plaque documented by intravascular ultrasound: A case report,CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 7 2009Hiroaki Kohno MD Abstract A 58-year-old male with dyslipidemia and coronary spastic angina suddenly experienced pain in the right limb while walking on November 1, 2008. Right-ankle brachial pressure index (ABI) was decreased (0.80) and left-ABI was normal (1.24). Bilateral ABI was normal during January 2008. Ultrasonography in the right-lower limb artery revealed severe stenosis in the right-popliteal artery with extended and large echolucent plaques containing an isoechoic area. We carried out lower limb angiography: subtotal occlusion of the popliteal artery was found. By intravascular ultrasound (IVUS), right-popliteal artery plaques were echolucent and eccentric; ulceration with a thin fibrous cap was noted. Percutaneous transluminal angioplasty was done and popliteal artery blood flow was improved. Right-ABI improved to 1.13 after 4 days. To prevent the progression and rupture of the plaques, lipid-lowering therapy and antiplatelet therapy were started. Plaque rupture of the popliteal artery was diagnosed by these characteristics on IVUS. Patients with peripheral artery disease may have plaque rupture similar to those with acute coronary syndromes who have identical unstable plaques and unstable atheromas. In addition to appropriate local revascularization, systemic therapy to stabilize the unstable plaque is indicated because failure to do so may cause recurrent events. © 2009 Wiley-Liss, Inc.
